Expand Your Glass Firing Horizons with the Olympic Kilns 259GFE: Designed for Big Ideas

Designed for Exceptional Performance on Challenging Glass Work

The Olympic Kilns 259GFE is the ultimate solution for glass artists working on large or uniquely shaped projects. With its spacious firing chamber measuring 37″ wide by 25″ front-to-back by 9″ deep, this oval kiln offers the flexibility and capacity needed for complex glass fusing, forming, and heat-treating tasks. Unlike traditional cylindrical or square kilns, the 259GFE’s oval design accommodates oversized pieces or multiple items, providing a larger, non-standard firing area that allows you to bring your most ambitious ideas to life.

Precision Heating for Consistent Results

The 259GFE is equipped with advanced heating elements located in both the lid and the body of the kiln, ensuring even and precise heat distribution throughout the firing chamber. The lid element provides the radiant heat necessary during the fusing stage, while the body elements manage the ramping up, cooling down, and annealing processes. For added control, the kiln includes an infinite switch that lets you adjust the intensity of the lid element, giving you full command over the firing process. Whether you're working on delicate glass art or larger, more demanding pieces, the 259GFE adapts to your needs with ease.

Built for Durability and Ease of Use

Constructed with a durable stainless steel jacket and supported by a sturdy 18″ tall metal stand, the 259GFE is built to endure the demands of continuous use in a professional studio. The kiln comes standard with the user-friendly Digital KilnStar controller, providing you with reliable and precise control over firing schedules. The KilnStar allows you to easily program and fine-tune your ramp-hold settings, ensuring consistent, perfect results every time. Additionally, the kiln's thoughtful design includes a pilot light for safety, peephole plugs for monitoring progress, and a detailed instruction manual for seamless setup and operation.

Upgrade Your Kiln with Customizable Options

For artists who want even more control, the 259GFE offers an upgrade to the Genesis touchscreen controller. The Genesis provides an intuitive, modern interface with expanded programming capabilities, making it easier to manage advanced firing profiles with greater precision. This optional upgrade adds an extra layer of convenience and customization for those seeking enhanced control over their firing process.

Optimize Your Firing Process with Tailored Accessories

Complete your kiln setup with a custom furniture kit tailored to your specific firing needs. The 259GFE furniture kit includes two layers of shelving, assorted square posts, ceramic paper, and a one-pound bag of kiln wash, ensuring that your glass pieces are evenly supported and properly heated during firing. Choose the standard kit or customize your own arrangement to suit your studio's unique requirements.

FAQs - Configuring Your Kiln

There are certain selections you must choose. And then there are options you can click on or ignore. The answers below should help you make the best choices for you.

 Which Kiln Voltage Should I Select?

Higher voltage means lower amperage draw and greater efficiency, which can save money long term. 240V and 208V cost the same—most home studios use 240V, while 208V is common in schools or large facilities. Amperage refers to the amount of electrical current a kiln draws—higher amps require heavier wiring and breakers.

What's The Difference Between Single-Phase and Three-Phase?

Single-phase is what almost all homes have. If your facility has three-phase, you can choose either—but three-phase is typically the better long-term option due to smoother power and improved efficiency.

Which Relay Option Do I Need?

Mechanical relays are standard and reliable. Solid-state relays (SSR) offer silent operation, faster cycling, greater precision, and longer lifespan—ideal for frequent or high-accuracy firings.

What Are The Differences Between Kiln Controllers?

The following controllers are used across kilns sold by Pottery Pulse. Not all models offer every option—available controllers are listed on each product page. Some kilns include only the standard controller, while most allow upgrades for added precision and convenience.

Olympic Kilns

  • Infinite Switch – Manual dial control for simple heat adjustments.
  • KilnStar – Digital controller with preset and user-defined programs.
  • Genesis – Advanced touchscreen interface with Wi-Fi and data logging.

Evenheat Kilns

  • Icon – Digital 3-button controller for straightforward firing.
  • RampMaster II – Manual digital controller for ceramic kilns; flexible ramp/hold programming.
  • RampMaster 3 – Updated version for glass kilns with refined interface.
  • Icon+ – Enhanced digital control with expanded profiles and precision.
  • TAP II – Smart touchscreen controller with Wi-Fi, data tracking, and remote access.

Hot Shot Kilns

  • Novus – “Set & Go” controller: set a target temperature and it does the rest (no segments).
  • Spark – Entry-level touchscreen controller with intuitive operation and limited program control.
  • TAP II – Smart touchscreen controller with Wi-Fi and real-time monitoring.

Jen-Ken Kilns

  • Orton AF3P 3-Button – Reliable and straightforward for basic firing.
  • Orton AutoFire 4000 12-Key – Expanded program capacity and fine control.
  • Orton AutoFire Slide Touchscreen – Modern, responsive touchscreen interface.
  • TAP II Touchscreen Smart Controller – Wi-Fi connectivity and real-time data tracking.

What Are Collars For?

Not all kilns can use a collar, but Olympic’s Hot Box kilns can be ordered with a collar to expand versatility. A blank collar simply adds height to the firing chamber, while a bead collar adds the same height and includes a built-in bead or annealing door for quick-access lampwork projects.

What Does The Power Interrupt Switch Do?

This safety feature automatically cuts power to the heating elements whenever the kiln lid or door is opened. It prevents accidental burns, protects elements, and resumes power only when safely closed. (Also called an automatic lid shutoff on Olympic kilns.)
